ATTACHMENT FOR MOTOR-DRIVEN VEHICLES.

Specification of Letters Patent.

Patented July 8, 1919.

Application filed April 26, 1919. berial No. 292,798.

T 0 all whom it may concern:

Be it known that I, J osnrn EARL STAUF' rmua cit zen of the UnitedStates, residing at Mount Dora, in the county of Union and State of NewMexico, have invented certain new and useful Improvements in Attachmentsfor Motor-Driven Vehicles, of which the followin is a specification,reference bein had to t e accompanying drawings.

' his invention relates to certain improvements in attachments for motordriven vehicles, and it is an ob'ect of the invention to provide a noveland improved attachment of this general character which may be e1nployed-with convenience and facility to extract a vehicle out of mud,sand, or the like.

It is'a'lso an object of the invention to provide'a novel andimprovedattachment of this eneral character which is adapted to coactwith the driving wheels of the vehicle so that the motor of the vehiclemay be employed to effect the desired withdrawal or extraction.

Another object of the invention is to provide a novel and improveddevice of this general character which may be readily collapsed orcompacted so that the same will occupy a minimum of space when not inuse, whereby the attachment may be conveniently carried by the vehicle.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improvedattachment. for motor driven vehicles whereby certain importantadvantages are attairied and the device rendered simpler, less expensiveand otherwise more convenient and advantageous for use, as will behereinafter more fully set forth.

The novel features of m invention will hereinafter be definitelyclanned.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein:

Figure 1 is a view in plan of an attachment constriicted in accordancewith an embodiment of my invention and in applied position, the coactingvehicle being diagrammatically indicated. I

Fig. 2 is a view in end elevation of one of the drums orspools as hereinincluded,

taken through the/drum or spool as illustrated in Fig. 2 with thecoacting portion of the wheel structure shown in fragment.

As disclosed in the accompanying drawings, my improved attachmentcomprises the drums or spools D, a cable C, and a spreader S and whichspreader S is adapted to be suitably engaged with a stationary member.-Each of the drums or spools D comprises a body portion 1 having endflanges (1 and b and the flange b is provided with the equidistantlyspaced arms 2 each having its outer extremity provided with a foot 3.The foot 3 has an opening 4 preferably oblong and through which a hookbolt 5 or the like is adapted to be directed to effect an engagement ofthe drum or spool D with a driving wheel \V of a motor driven vehicle.The second flange ais rovided with an open slot 6 preferably radiallydisposed and for a purpose which will be hereinafter more particularlyreferred to.

The opposite end portions of the cable C are knotted as indicated at 7so that when said extremities of the cable are disposed through theslots 6 of the drums or spools D, the end portions of the cable will becaused to wind around the drums or spools D upon the rotation of thewheels W and particularly when said wheels are driven by the motorcomprised in the vehicle.

The cable C is of such length that when the extremities thereof areengaged with the drums or spools D, the folded portion of the cable willbe positioned a desired distance in advance of the vehicle. A spreader Scoacts with the folded portion of the cable G and, as is particularlyillustrated in the accompanying drawings, said spreader S is insubstantially the form of an equilateral triangle with its apexforwardly directed. The apex of the separator S is provided with aforwardly directed extension or arm 8 to which is suitably secured anend portion of a chain 9 or other flexible member. The chain or member 9includes the spaced annular members or rings 10 adapted to be engagedover a stake ll driven into the ground or with any other suitablesupport.

The opposite end portions of the base 12 of the spreader S and theextension or arm 8 are provided with the pulleys 14 over which the cableC is directed. whereby the operation of my improved attachment ismaterially facilitated.

It is also preferred that the spreader S proved attachment is materiallycomprise separable sections so that when the device is not in use thesame may be readily compacted to occupy a minimum of space so that itsstorage within the vehicle is materially facilitated.

in the present embodinn-ut of my invention, the base 12 and the sidemembers 15 each comprise two separable sections 16 maintaincd inassembled relation by a coupling sleeve 17. The sleeve 17 is permanentlyattached to one of the sections 16 and detachabl secured to the secondor coactin section 16 y a removable bolt 18 or the hie.

The spreader S serves t0,keep the stretches of the rope from hugging orcontacting with the front wheels of the vehicle and also serves tomaintain the stretches of the rope free of the running boards of apleasure car or the like. It is also to be particularly stated that thepulleys 14 facilitate the use of a continuous rope and assure therequisite tension during a pulling operation.

It is also to be stated that it is preferred that the cable C windaround the drums or spools D from below, whether pulling the vehicleforwardly or rearwarly, as by this arrangement the functioning of myimfacilitated.

From the foregoing description, it is thought to be obvious that anattachment for motor driven vehicles constructed in ac Cordunce with myinvention is particularly well adapted for use by reason of theconvenience and facility with which it may be assembled and operated,and it will also be obvious that my invention is susceptible of somechange and modification without dcparting from the principles and spiritthereof and for this reason (io not wish to be understood as limitingmyself to the precise arrangement and formation of the several partsheroin shown in carrying out my most invention in practice except ashereinafter claimed.

I claim:

1.. An attachment of the cl'iaractcr described comprising, incombination, drums adapted to be secured to the driving wheels of amotor driven vehicle, a cable having its extremities engaged with saiddrums to wind therearound, a spreader coacting with the intermediateportion of the cable, said spreader being substantially triangular inform, pulleys carried by the ends of the base of the spreader and theapex portion thereof, and anchoring means carried by the apex portion ofthe spreader, the apex portion of the spreader being provided with aforwardly directed arm with which the anchoring means is engaged andwhich carries the pulley coacting with the apex portion of the spreader.

2. An attachment of the character described comprising, in combination,drums adapted to be secured to the: driving wheels of a motor drivenvehicle, a cable having its extremities engaged with said drums to windthcrcaround, a spreader coacting with the intermediate portion of thecable, said spreader being substantially triangular in form, pulleyscarried by the ends of the base of the spreader and the apex portionthereof, anchoring means carried by the apex portion of the spreader,said spreader comprising separable sections and coupling sleevescoacting with the adpiccnt sections of the spreader for maintaining thesame in assembled relation.

In testimony whereof I hereunto afiix my signature in the presence oftwo witnesses.
